Like all OsidLists, BrokerConstrainerList provides a means for accessing BrokerConstrainer elements sequentially either one at a time or many at a time. Examples:

while (bcl.hasNext()) {
     BrokerConstrainer constrainer = bcl.getNextBrokerConstrainer();
}

or

while (bcl.hasNext()) {
     BrokerConstrainer[] constrainers = bcl.getNextBrokerConstrainers(bcl.available());
}
